Customized sizing for all of your pipe connection needs.


Improving Processes. Reducing Costs.

In addition to the wide range of available standard end connection options, Ultra Tech can provide customized sizes and configurations to meet the requirements of your system. For snap coupling and two-bolt coupling options, consult factory.


Selections of the appropriate option, or combination of options, is dictated by maintenance considerations, performance expectations, life cycle, and other variables.


While end options can, in most cases, be installed in the field utilizing proper procedures, improved performance will result when factory fitted. Care must be taken to cool the inner surface of the pipe wall to prevent tempering, thus softening of the martensitic microstructure. Consideration must also be given to the end option bore. With induction hardening and the change in microstructure, the pipe actually increases in diameter. The pipe diameter and the end option bore must fit for integrity.
